My one "never sell" watch is nothing special tbh. It's a mass produced ana-digi that may well mean nothing to anyone else, but that to me?
Is near priceless.
It's a Citizen Pro-master jp3040-55w. It was gifted to me from my wife in June 2004 as my 1st ever father's Day gift.
It was a watch that a lot of thought went into on her part.
I was diving quite a bit back then and had a similar albeit steel, watch stolen a couple of years earlier.
Anyway my wife went and spoke to friends, got some recommendations and bought me the titanium Promaster.
It was given to me as from her and our son, so it has huge emotional and sentimental value to me.
We lost her suddenly in 2007 and that watch and the happiness it evokes for me always brighten a dark day when I'm struggling.
It was away recently for a crystal replacement and I missed it something awful
I have other more expensive watches in my box, but none are more valuable to me.
